The Foo Fighters have been big Obama supporters since 2008. They played a concert at the White House for military families on July 4, 2009. And in November, the band's lead singer Dave Grohl told Red Bulletin that he was "absolutely" supporting the president's bid for a second term.

"He's got the toughest job on earth," Grohl said. "I would hate to hand the administration over to another party that is just focused on corporations, greed and money. You know, I'm a fun, peace-loving guy, but sometimes the right wing gets a little too selfish."
